hello all !!!
I want to simulate a circuit in "config" mode which has the following:
1) PMOS and NMOS from UMC_180nm library
2) a ideal comparator from ahdl library
3) a block whose functionality is written in verilog
4) an opamp using MOSs

When i am simulating it  using "ams" simulator , it is showing the following errors:


ncelab: *E,CUCFUN: instance 'M1' of the unit 'p_18_mm' is unresolved in 'new_afe_bunu.switch:schematic'.
ncelab: *E,CUCFUN: instance 'M0' of the unit 'n_18_mm' is unresolved in 'new_afe_bunu.not:schematic'.

Cn anyone help me how to run my simulation??????
